What's the easiest way to make external USB drives automount, without adding them to fstab? It should just work even if someone else hands me their flash drive.
I'm running sway on Arch if that matters.

This. I also use udiskie on sway, works perfectly.

DEs dont use mount and fstab, they use udisks2 which works with polkit, GUI prompts or rootless.

Using udisksctl prevents a ton of breakages.

I dont know about how autostart files work anymore, I always thought just place stuff in ~/.config/autostart but now those dont work anymore on KDE, sometimes.

I think you use your init system for that. If you go fully rootless, you can create a user systemd service that mounts the drive.

mkdir -p ~/flashdrive

cat <<EOF > ~/.config/systemd/user/flashdrive-mount.service
[Unit]
Description=Mount flash drive on /dev/sda
#After=multi-user.target

[Service]
Type=oneshot
ExecStart=/usr/bin/udisksctl mount --block-device /dev/sda --mount-point /home/$USER/flashdrive
RemainAfterExit=true

[Install]
WantedBy=multi-user.target
EOF

systemctl --user enable --now flashdrive-mount.service

Not sure if After=multi-user.target and WantedBy=multi-user.target twists the space time continuum or something.

I am always kinda confused by those targets, as you must state one.

You shouldn't just automount external drives. That's a recipe for trouble.

What's wrong with manually mounting them? Pretty sure the desktop environments also require you to push a button (eg, select the drive in file manager) to mount external USB drives.

WTF? I'm automounting my home directory from an external ssd usb for ages now. What is the disaster that could happen you're referring to?

[-] Strit@lemmy.linuxuserspace.show 12 points 1 day ago

If that's the case, then you should answer the OP with how it's set up. OP is specifically asking how to do it with random drives other people hands them, not trusted drives always connected.

What is the disaster that could happen you’re referring to?

Auto mounting random USB sticks has never been wise. No telling what random malware they contain.

What would be the difference if it doesn't automount it, and I instead need to mount it manually?
I mean, it's a USB stick which I just plugged into my laptop and want to access.
If I don't trust it, I'm not plugging it in.

What malware spreads automatically from just mounting the drive?

So it's either using auto run to execute malicious code (not an issue in Linux), or it acts as a keyboard and sends malicious command - which would work regardless of the USB partition being mounted or not.

Oh sorry, guess I missed the random drives part. You're absolutely right in that regard. Also, I use fstab to setup automount, so can't help op with this.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
